H(t)=-16t^2+48t+4. what would be the height of the ball after 2 seconds

Answer 1

Hi Jamie

In your function, does H represent height and t represent time in seconds?

If so, you just need to plug the number into your function.

Make sure you understand and define the variables and their relationship in your function.

H(t) = -16t² + 48t +4

H(2) = -16(2)² + 48(2) + 4

Can you continue from here and get a value for H.

If you can also graph your function at desmos.com to confirm the height at t=2 seconds
